Germany actually did not encourage Austria-Hungary to declare with Serbia since it was not the first country to declare war on another during World War I. Austria-Hungary and Serbia were the first countries to enter World War I, only weeks before Germany joined in to help Austria-Hungary and the other Central Powers.
